<div class="textblock"><h2>The Parola Library </h2>
<p>The Parola library is implemented to work with the MD_MAX2XX library. It depends on the MD_MAX72xx library for hardware control and will run on all hardware supported by that library. The MD_MAX72XX library can be found <a href="http://github.com/MajicDesigns/MAX72xx">here</a>.</p>
<p>This software library implements functions to simplify the implementation of text special effects on the Parola display.</p><ul>
<li>Left, right or center text justification in the display field.</li>
<li>Text scrolling, text entering and exit effects.</li>
<li>Control display parameters and animation speed.</li>
<li>Multiple virtual displays (zones) in each string of LED modules.</li>
<li>User defined fonts and/or individual characters substitutions.</li>
<li>Double height and vertical displays.</li>
<li>Support for mixing text and graphics on the same display.</li>
</ul>
<p>The latest copy of the Parola Library can be found at the <a href="http://github.com/MajicDesigns/Parola">Parola distribution site</a>.</p>
